摘要: BACKGROUND.: Cystic lymph node metastasis (CLNM) is commonly found in human papillomavirus (HPV)-associated tonsillar squamous cell carcinoma (SCC). The aim of this study was to compare the accuracy detecting cystic from SCC between contrast-enhanced CT, (18)F- fluorodeoxyglucose-positron emission tomography (FDG-PET), non-enhanced (18)F-FDG-PET/CT, and (18)F-FDG-PET/CT. METHODS.: Thirty-four patients with a undergoing pretreatment (18)F-FDG-PET/CT followed by neck dissection as standard reference were included. CT part, (18)F-FDG-PET assessed separately for correct N classification differentiation N0 versus N+. RESULTS.: Contrast-enhanced are equally accurate staging. Regarding pN0 pN+, superior (p = .017). CONCLUSION.: perform better than CLNM SCC. Therefore, scheduled we strongly suggest performing which not routine most centers. (c) 2010 Wiley Periodicals, Inc. Head Neck, 2010.
